EGG BEATEB.

Application filed April 1, 1 92s.

This invention relates to certain improvements in heaters and has relation more particularly to a device of this character especially designed and adapted for use in 5 the beating o'r agitating of eggs, batter or the like, and it is an object of the invention to provide a device of this kind comprising a rotatable shaft having associated therewith a plurality of beating arms, said arms being adjustable substantially radial with respect to the shaft.

It is also an object of the invention to provide a device of this kind comprising a rotary agitating element which may be readily and conveniently moved in a direction lengthwise of its axis when the occasions of practice may so require.

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved beater whereby -certain important advantages are attained and the device rendered simpler, less expensive and otherwise more'c'onvenientand advantageous for use, as will be hereinafter more fully set forth. I

The 'novel features of'my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe .the same with reference to the accompanying drawings, wherein V Figure 1 is a view in side elevationuof a beater constructed in accordance with an embodiment of my invention, a coacting table andcontainer being fragmentarily indicated by broken lines;

As herein set forth, denotes a supporting "bracket which is provided at one end portion with the laterally disposed gparallel arms 1 through one of which is threaded a This member 2 coacts it in a vertical positionfito the marginal. portionof atable or other support. H p

The upper portion of the bracket B is disposed on a predetermined curvature and is provided at its upper free end with a vertically disposed barrel 3 open at its opposite' ends antl'provided'inthe for-wardportion of its wall with a longitudinally disposed slot 4: open at the lower endof the barrel 3. This slot tadj acentto its opposite ends is 'in communication with the transversc'lyor circumferentially disposed slots 5 extending beyond-opposite sides of the slot 4:.

The upper end portion of the barrel dis "closed by ayplugfi maint-ained inapplied positionby the: pin '7 or the like.

Thezplug 6 at its axial center is{providedwith-anupstand- Hit) ill)

ing shank 8 upon which is loosely mounted an idler beveled pinion 9. This pinion 9 is held in applied position by a cap nut 10 threaded upon the upper portion of the shank 8. Interposed between the applied cap nut 10 and the pinion 9 are the antifriction members or ball bearings 11 and interposed between the plug 6 and the applied pinion 9 are the anti-friction members or bearings 12.

h leshing with the pinion 9 is the power gear 14 of desired diameter and which is freely mounted upon the outstanding pin or stub shaft 15 carried by the barrel 3, the

hub 16 of the gear 14 and said shaft 15 having associated therewith ball bearings 17 or other suitable anti-friction members. The peripheral portion of the gear 14 is provided with an outstanding handle 17 of any preferred type which provides means whereby the gear 14 may be manually operated.

Extending inwardly from the bracket B is an arm 18, the free end portion underlying the barrel 3. Extending freely through said free end portion of the arm 18 is the upper spindle section 19 the upper portion of which being disposed within the barrel 3 and having secured thereto the spaced collars 20. Arranged between the lower end of the barrel 3 and the adjacent part of the end portion of the arm 18 is a pinion or gear 21 meshing with the gear 14. The spindle section 19 is freely disposed through the axial center of the gear 21 but held thereto for rotation therewith by the key 22 suitably fixed within the bore of the gear 21 and extending within the key seat or groove 23 extending lengthwise of the spindle section 19. This key seat or groove is also continued along the lower spindle section 24 coupled to the lower end of the spindle section 19 by a conventional threaded couplin 25.

Freely engaged with the inserted end portion of the spindle section 19 between the collars is the enlarged end portion 26 of a lift lever L while the opposite restricted portion 27 of the lever L extends exteriorly of the barrel 3 through the slot 4. The extended portion 27 permits a ready lifting of the spindle section 19 and its connected section 24 when desired and when at the limit of such upward movement, the extended portion 27 may be readily returned to enter either portion of the upper lateral slot 5 to maintain the spindle sections raised. When the spindle sections are in their lowered position they may be readily held in such position by causing the restricted portion 27, or arm as it may be called of the lever L, to enter within the lower slot 5 at either side of the slot 4.

Interposed between the arm 18 and the gear 21 are the ball bearings 28 or other suitable anti-friction members.

Keyed or otherwise fixed to the lower end portion of the spindle section 24 is a hub 29 from which radiates the arms 30. The arms 30 are herein disclosed as four in number and equi-distantly spaced, said arms 30 and hub 29 constituting what may be termed a spider.

Each of the arms 30 is longitudinally slotted, as 31 and through which is disposed a bolt 32 carried by the tail piece 33 of an agitating paddle or blade 34. This bolt 32 has associated therewith a nut preferably of a wing type whereby the blade 3-1-1- n'iay be clamped at any desired point along the slot 31. The paddle or blade 34 proper is disposed lengthwise on a slight curvature as illustrated in Figure 9 and is formed somewhat after the fashion of a spoon bowl.

livotally connected, as at 36, with the paddle or blade 34 is an end portion of a rigid arm or link 37, the opposite end portion of which being pivotally connnected, as at 38, with a bifurcated arm 39. This arm 39 radiates from a hub 40 which snugly surrounds a sleeve 41. The arm 39 together with the hub 40 constitute what may be termed a spider. The sleeve 41 is slidably mounted upon the spindle section 24 and the opposite end portions of the wall of the sleeve have the bayonet slots 42. W hen the sleeve 41 is in its uppermost position, an outstanding pin 43 is engaged in the upper slot 42 to lock said sleeve 41 in such position, said locking action being readily effected upon slight rotation of the sleeve 41. When the sleeve 41 is in its lowermost position, a second outstanding pin 44 carried by the spindle section 24 is received within the lower slot 42 to effect the desired locking.

Although not illustrated, it is to be understood that if desired there may be interposed between the hub 40 and the sleeve 41 suitable anti-friction members to facilitate the desired turning movement of the sleeve 41 when locking or interlocking the same in either its raised or lowered position.

l i lien the paddles or blades 34 are in their innermost or retracted positions, the sleeve 41 is locked in its upper position and when the blades are substantially fully extended, the sleeve 41 is locked in its lowered position. This adjustment of the blades or paddles 34 is in accordance with the requirments of practice and especially as may be determined by the dimensions of the receptacle containing the egg, batter or the like to be beaten or agitated.

vVhen during a working operation, it is desired to lift the blades or paddles 34 out of the material to be beaten or agitated, it is only necessary to move the lifting lever L in the position to permit the restricted portion 27 to readily pass through the slot 4 when pull is imposed upon said lever.

llii

The upper portion of the lower spindle section 24: is provided with the flattened faces 45 to provide means whereby a wrench or other implement may be readily engaged with the spindle section to facilitate its application or removal with respect to the upper spindle section 19.

From the foregoing description it is thought to be obvious that a beater constructed in accordance with my invention is particularly well adapted for use by reason of the convenience and facility with which it may be assembled and operated, and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in prac tice except as hereinafter claimed.

I claim 1. An egg beater, including a rotatable L spindle member, a hub at the outer end thereof, agitating blades extending radially from said hub, means for adjustably mounting said blades to permit adjustment of said blades toward and away from the hub and means for adjusting said blades in the arc of a circle independent of the first adjustable means.

2. An egg beater, including a rotatable spindle, a hub at the outer end thereof, arms extending radially from the hub having longitudinal slots, a plurality of agitating blades, bolts carried by said blades and adjustable in said slots whereby said blades may be adjusted toward and away from the hub and means mounted upon the spindle and having connection with the blades whereby to adjust said blades in the arc of a circle.

3. An egg beater, including a rotatable spindle, a hub at the outer end thereof, arms extending radially from said hub and having longitudinal slots, a plurality of agitating blades, bolts carried by said blades and ad justable in said slots whereby the blades may be adjusted toward and away from the hub, a sleeve slidably mounted upon the spindle and links connecting the sleeve with the blades to provide for adjustment of the blades in the arc of a circle.

In testimony whereof I hereunto affix my signature.

RICHARD l/V. JACKSON.
